ALBERT F. BRANDENBURG, OF DAYTON, OHIO.

OFFICE-DOOR INDICATOR.

SPECIFICATION forming part of Letters Patent No. 537,813, dated April 23, 1895.

. Application tiled May 24, 1894. Serial No. 512,390- (No model.)

To @ZZ whom tm/ty concern:l

Be it known that I, ALBERT F. BRANDEN- BURG, of Dayton, county of Montgomery, State of Ohio, have invented a new and useful Improvement in Office-Indicators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of vthis specification.

My invention relates to new and useful improvements in office indicators, of the class adapted to be attached to the doors of offices; and has for its obj ect, to provide an improved cnice indicator by means of which notice may be given ofthe absence of the occu pant, where he may be found, and the'time of his return.

To this end my invention consists of means that will be fully described in the specification, and the specilic points of novelty set forth in the claims.

Referring to the annexed drawings forming a part of the specification, Figure l, represents a front elevation of the device; Fig. 2, a front elevation with the door removed, and the lower portion broken away; Fig. 3, an enlarged detached, detail view of the strip that supports the occupants name; Fig. 4, 4an end view of the same; Fig. 5, an enlarged, de-

tached, detail view of the rod for maintaining the indicator cards compactly, when the use of the door is dispensed with; Fig. 6, a vertical section of the device.

The inclosing case consists of the rear portion A, having hinged thereto, a front portion or door A', with' a glass panel B, throughl which may be seen the notice.

O represents a series of cards made of any suitable pliable material, that are attached at their lower extremity, one over the other in a pack, to the inside of the rear portion of the case. Each of these cards contains different information indicating the absence of the occupant of the office, and of course, they may bear any information adapted to the character of the business of each individual.

D is a sheet metal plate hinged at its lower end to the bottom of the case A, and having over-turned edges (d) beneath which is secured a card bearing figures denoting the time of day, and index fingers pointing to said time.

(e) is a linger-piece by which the plate D may be opened or closed upon "its hinge.

(f) indicates metal rods projecting vertically from the plate D, on the upper ends of which,is pivoteda transverse strip E adapted to contain thename of the occupant of the oftice. This strip may be turned to expose either side, in case the oiice has two occupants, and one only is absent.

The plate D in addition to serving the purpose of supporting the clock dial, also holds the cards that have been turned down, in place, and is itself, maintained in position either by the glass B when the case is provided with the doorA, or by the transverse rod (g) when the door is dispensed with.

Then the device is used without the door, it is usuallyplaced on theinside of the ofiice door, and is visible through the glass panel usually found in office doors. The rod (g) is movably attached to the rear of the case A, by staples (g) as shown in Fig. 2 and has its ends turned and provided with finger-pieces (i). The dotted lines in Fig. 2 show the position to which theends of said rod are turned to lock the plate D and rods f) to hold the cards in position which it does by said fingerpieces coming in contact with the rods (f) when turned downward to the position indicated by the broken lines, Fig. 2.

The operation of the device is understood' from Fig. l. Should it be desired to exhibit a card other than the one shown, the card to be exposed is turned up if among those turned down, as shown in Fig. 3, or if not already turned down, those remaining raised, in front of it, are turned down; and the desired card exposed; it being understood that each card is printed on one side only, vizz-the side toward the front when the cards are standing up. The index hands are then turned at the proper time.

When the device is placed on the outside of the office door, the door A is employed to prevent meddling with the indicator. i Its attachment to the office door may be in any suitable manner. If employed on the outside of the door, I prefer to attach it so the iiange of the cover A will be closed between the door and the frame in a manner similar to that desaisis scribed in Letters Patent No. 500,316, granted to myself.

Having described my invention, I claiml. In an office indicator, the combination with the case; of a series of cards, each card containing,r information printed thereon and attached at their lower ends, one over the other, to the rear of the case so as to permit of said cards being turned down to enable any card in the rear to be seen, the plate D bearing a time dial and index hands, hinged at its lower end to the bottom of the case, the rods (f) attached to said plate, and the strip E mounted on said rods, and means for maintaining the indicator cards and the plate D in proximity to each other, as herein described.

2. The combination ofthe case A, a series of ALBERT F. BRANDENBURG.
